Winterpark is my preferred place to ride along the Front Range. It's the fourth largest resort in Colorado I believe. That said, people kind love it or hate that place. Mostly because it's not an obvious resort, you really have to learn it to find the fun stuff. Park wise they have always been lagging. Every year there is a new focus on park and yet the don't seem to match up to their counterparts in Summit County.

Granby is a mountain town. It's pretty rough around the edges. Fraser Valley is nice enough though and sees far less traffic than the I70 corridor. You could end up in much worse places for sure.
